pwfu

Just a little CLI random password generator.

Why?

Because sometimes you need to generate a password and you don't want to think about it that much.

Implementation

Just a minimal CLI wrapper over the node crypto library.

Installation

npm i -g pwfu

Definitions

There are a few concepts involved in generating a password with pwfu:

• hash
• secret
• salt
• seed

A hash is just the output of the function we use to produce our password. The secret is used to salt the password. The seed is used to generate a hash. The secret is just something you store locally that helps the program to generate hashes that are unique. This is called salting. The seed is optional, but you can use if you want to reproduce a hash. If you have the same secret and seed you'll get the same hash.

Usage

# First run you need to give a secret for salting your hashes
> pwfu
Tell me a secret so I can salt your passwords:
# prompts for user input
[This can be pretty much whatever you want]
# response
Mmmm... what a salty string.
# Just give me a random password!
> pwfu

Deterministic passwords

This can be useful if you want to create a complex password from a unique secret and seed.

# New facebook password
> pwfu -s My little secret
> pwfu Zuck no more

# Secrets make passwords generated from seeds deterministic
> pwfu Zuck no more

Disclaimer

If you want to use this for anything other than locally generating unique passwords, I won't judge but that probably isn't a very good idea.
